Field of Invention

This invention relates to the field of compounds, pharmaceutical compositions, and methods of using the compounds and compositions containing them. This invention relates more particularly to the field of benzimidazole compounds and pharmaceutical compositions thereof, methods of activating AMPK with the compounds, and methods of treating and/or preventing disease with the compounds.

Technical Background

Adiponectin is a protein hormone exclusively expressed in and secreted from adipose tissue and is the most abundant adipose-specific protein. Adiponectin has been implicated in the modulation of glucose and lipid metabolism in insulin-sensitive tissues. Decreased circulating adiponectin levels have been demonstrated in some insulin-resistant states, such as obesity and type 2 diabetes mellitus and also in patients with coronary artery disease, atherosclerosis and hypertension. Adiponectin levels are positively correlated with insulin sensitivity, HDL (high density lipoprotein) levels and insulin stimulated glucose disposal and inversely correlated with adiposity and glucose, insulin and triglyceride levels. Thiazolidinedione drugs, which enhance insulin sensitivity through activation of the peroxisome proliferator-activated receptor-γ, increase endogenous adiponectin production in humans.

Adiponectin binds its receptors in liver and skeletal muscle and thereby activates the 5′-AMP-activated protein kinase (AMPK) pathway. Adiponectin receptors 1 and 2 are membrane-bound proteins found in skeletal muscle and liver tissue. Being a multi-substrate enzyme, AMPK regulates a variety of metabolic processes, such as glucose transport, glycolysis and lipid metabolism. It acts as a sensor of cellular energy homeostasis and is activated in response to certain hormones and muscle contraction as well as to intracellular metabolic stress signals such as exercise ischemia, hypoxia and nutrient deprivation. Once activated, AMPK switches on catabolic pathways (such as fatty acid oxidation and Glycolysis) and switches off ATP-consuming pathways (such as lipogenesis). Adiponectin improves insulin sensitivity by directly stimulating glucose uptake in adipocytes and muscle and by increasing fatty acid oxidation in liver and muscle, resulting in reduced circulating fatty acid levels and reduced intracellular triglyceride contents. Moreover, adiponectin decreases glycogen concentration by reducing the activity of glycogen synthase. Adiponectin also plays a protective role against inflammation and atherosclerosis. It suppresses the expression of adhesion molecules in vascular endothelial cells and cytokine production from macrophages, thus inhibiting the inflammatory processes that occur during the early phases of atherosclerosis.

SUMMARY

In view of the foregoing, we recognized that new therapeutic agents that activate the AMPK pathway may be useful and therefore desirable for treating disease states associated with circulating adiponectin levels, such as type II diabetes, atherosclerosis and cardiovascular disease.

In another aspect, the present invention comprises pharmaceutical compositions comprising a compound according to any one of the preceding aspects of the invention or any embodiment thereof, together with a pharmaceutically acceptable excipient, diluent, or carrier.

While not intending to he bound by theory, the inventors surmise that compounds of structural formulae (I)-(IIIk) are direct activators of AMPK, thereby activating the AMPK pathway. In one embodiment, the present compounds selectively activate one isoform of AMPK. For example, certain compounds selectively activate the α₂β₂γ₃ isoform, such as with an EC₅₀ of two-fold, three-fold or even twenty-fold less than an EC₅₀ for another isoform. Such selectivity can confer tissue selectivity since different AMPK isoforms are expressed in different tissues. In particular the α₂, β₂ and γ₃ subunit isoforms are found in skeletal muscle. Thus, in certain embodiments the present compounds are selective activators of AMPK in skeletal muscle.

Activation of the AMPK pathway has the effect of increasing glucose uptake, decreasing glycogen synthesis and increasing fatty acid oxidation, thereby reducing glycogen, intracellular triglyceride and fatty acid concentration and causing an increase in insulin sensitivity. Because they activate the AMIPK pathway, compounds of structural formulae (I)-(IIIk) should also inhibit the inflammatory processes which occur during the early phases of atherosclerosis, Accordingly, compounds of structural formulae (I)-(IIIk) can be useful in the treatment of type II diabetes and in the treatment and prevention of atherosclerosis, cardiovascular disease, obesity and non-alcoholic fatty liver disease.

Accordingly, another aspect of the invention is a method of activating the AMPK pathway. According to this aspect of the invention, a method for activating the AMPK pathway in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, prodrug, solvate, hydrate, N-oxide or composition described above.

Another aspect of the invention is a method of increasing fatty acid oxidation in a cell. According to this aspect of the invention, a method of increasing fatty acid oxidation in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, prodrug, solvate, hydrate, N-oxide or composition described above. Acetyl Co-A carboxylase (ACC) catalyzes the formation of malonyl Co-A, a potent inhibitor of fatty acid oxidation; phosphorylation of ACC greatly reduces its catalytic activity, thereby reducing the concentration of malonyl Co-A and increasing the rate of fatty acid oxidation. Because compounds of the invention can increase the rate of phosphorylation of ACC, they can reduce the inhibition of fatty acid oxidation and therefore increase its overall rate.

Another aspect of the invention is a method of decreasing glycogen concentration in a cell. According to this aspect of the invention, a method of decreasing glycogen concentration in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, prodrug, solvate, hydrate, N-oxide or composition described above.

Such methods are useful for studying the AMPK pathway and its role in biological mechanisms and disease states both in vitro and in vivo.

In certain embodiments, the compounds disclosed herein affect lipid signaling pathways. For example, in some embodiments, the compounds up-regulate ceramidase activity. Ceramide is a central player in sphingolipid metabolism, and is the immediate precursor of sphingomyelins and glycosphingolipids as well as the bioactive products sphingosine and sphingosine-1-phosphate. Moreover, endogenous ceramide itself mediates, at least in part, the actions of a variety of stimuli on cell differentiation, apoptosis, and growth suppression. Ceramide is deacylated by ceramidase to form sphingosine, which is in turn phosphorylated to sphingosine-1-phosphate by sphingosine kinase.

Elevated ceramide levels have been shown to induce cell apoptosis, differentiation and senescence. Moreover, elevated ceramide levels are linked to a variety of diseases and disorders, including, for example, Batten's disease, inflammatory bowel diseases, diffuse intravascular coagulation, fever, protein catabolism and/or lipid depletion, hepatosplenomegaly associated with inflammatory or metabolic liver diseases, endomyocarditis, endolithial cell and leucocyte activation, capillary thrombosis, meningo-encephalitis due to infectious agents, complications in organ transplantation, rheumatoid arthritis and connective tissue diseases, autoimmune diseases, hyperthyroidism, damage by radiation/chemotherapy agents and chronic fatigue syndrome.

Up-regulating, ceramidase function (and therefore reducing the concentration of ceramide) can be used to treat disorders involving deficient cell proliferation (growth) or in which cell proliferation is otherwise desired, for example, degenerative disorders, growth deficiencies, lesions, physical trauma, and diseases in which ceramide accumulates within cells, such as Fabry disease. Other disorders that may benefit from the activation of ceramidase include neurodegenerative disorders such as Alzheimer's disease and amyotrophic lateral sclerosis and disorders of aging such as immune dysfunction, as well as disorders, such as those listed above, linked to elevated ceramide levels.

The compounds, salts, prodrugs, V-oxides, solvates and hydrates described herein can be administered, for example, to a mammalian host to retard cellular responses associated with the activation of the ceramide-mediated signal transduction pathway. The compounds can be useful, for example, in providing protection against cell senescence or apoptosis, such as occurs as a result of trauma (for example, radiation dermatitis) and aging (for example, of the skin or other organs).

Another embodiment is a method for up-regulating ceramidase function in a cell (either in vivo or in vitro), the method including contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, prodrug, N-oxide (or solvate or hydrate thereof) or composition of a compound described above.

Various applicable diseases and disorders are described above. In certain embodiments, the subject has a ceramide level higher than about 50 pmol/10⁶ cells.

Moreover, since some drugs can induce high levels of ceramide, the compounds, salts, prodrugs, N-oxides, solvates and hydrates described herein can be usefully co-administered with such drugs in order to at least partially ameliorate this effect. For example, in certain embodiments, an effective amount of a compound, pharmaceutically acceptable salt, prodrug, N-oxide (or solvate or hydrate thereof) or composition as described herein is co-administered with a corticosteroid (for example, dexamethasone), an anti-inflammatory (for example, indomethacin), an antiviral (for example, interfereon), immunosuppressant (for example, cyclosporin), a chemotherapy agent (for example, adriamicin), and immunopotentiant (for example, an immunoglobulin or a vaccine), or an andocrinological agent (for example, metimazole). As the person of skill in the art will appreciate, co-administration contemplates not only administration at the same time, but also administration at different times, but with tinge-overlapping pharmacological effects.

Definitions

Terms used herein may be preceded and/or followed by a single dash, “-”, or a double dash, “=”, to indicate the bond order of the bond between the named substituent and its parent moiety; a single dash indicates a single bond and a double dash indicates a double bond or a pair of single bonds in the case of a Spiro-substituent. in the absence of a single or double dash it is understood that a single bond is formed between the substituent and its parent moiety; further, substituents are intended to be read “left to right” unless a dash indicates otherwise. For example, arylalkyl, arylalkyl-, and -alkylaryl indicate the same functionality.

For simplicity, chemical moieties are defined and referred to throughout primarily as univalent chemical moieties (e.g., alkyl, aryl, etc.). Nevertheless, such terms are also used to convey corresponding multivalent moieties under the appropriate structural circumstances clear to those skilled in the art. For example, while an “alkyl” moiety can refer to a monovalent radical (e.g. CH₃—CH₂—), in some circumstances a bivalent linking moiety can be “alkyl,” in which case those skilled in the art will understand the alkyl to be a divalent radical (e.g, —CH₂—H₂—), which is equivalent to the term “alkylene.” (Similarly, in circumstances in which a divalent moiety is required and is stated as being “aryl,” those skilled in the art will understand that the term “aryl” refers to the corresponding divalent moiety, arylene). All atoms are understood to have their normal number of valences for bond formation (i.e., 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S). Nitrogens in the presently disclosed compounds can be hypervalent, e.g., an N-oxide or tetrasubstituted ammonium salt. On occasion a moiety may be defined, for example, as (A)_(a)-B—, wherein a is 0 or 1. In such instances, when a is 0 the moiety is B— and when a is 1 the moiety is A-B—.

As used herein, the term “alkyl” includes alkyl, alkenyl and alkynyl groups of a designed number of carbon atoms, such as 1 to 6 carbons (i.e., inclusive of 1 and 6), 1 to 6 carbons, 1 to 3 carbons, or 1, 2, 3, 4, 5 or 6. The term “C_(m)-C_(n)alkyl” means an alkyl group having from m to n carbon atoms (i.e., inclusive of m and n). The term “C_(m)-C_(n)alkyl” means an alkyl group having from m to n carbon atoms. For example, “C₁-C₆alkyl” is an alkyl group having from one to six carbon atoms. Alkyl and alkyl groups may be straight or branched and depending on context, may be a monovalent radical or a divalent radical (i.e., an alkylene group). In the case of an alkyl or alkyl group having zero carbon atoms (i.e., “C₀alkyl”), the group is simply a single covalent bond if it is a divalent radical or is a hydrogen atom if it is a monovalent radical. For example, the moiety “—(C₀-C₆alkyl)-Ar” signifies connection of an optionally substituted aryl through a single bond or an alkylene bridge having from Ito 6 carbons. Examples of “alkyl” include, for example, methyl, ethyl, propyl, isopropyl, butyl, iso-, sec- and tert-butyl, pentyl, hexyl, heptyl, 3-ethylbutyl, 3-hexenyl and propargyl. If the number of carbon atoms is not specified, the subject “alkyl” or “alkyl” moiety has from 1 to 6 carbons.

The term “haloalkyl” is an alkyl group substituted with one or more halogen atoms, e.g. F, Cl, Br and I. A more specific term, e.g., “fluoroalkyl” is an alkyl group substituted with one or more fluorine atoms. Examples of “fluoroalkyl” include fluoromethyl, difluoromethyl, trifluoromethyl, pentafluoroethyl, hexafluoroisopropyl and the like. In certain embodiments of the compounds disclosed herein, each haloalkyl is a fluoroalkyl.

The term “aryl” or “Ar” represents an aromatic ring system having a single ring (e.g., phenyl) which is optionally fused to other aromatic hydrocarbon rings or non-aromatic hydrocarbon rings. “Aryl” includes ring systems having multiple condensed rings and in which at least one is carbocyclic and aromatic, (e.g., 1,2,3,4-tetrahydronaphthyl, naphthyl). Examples of aryl groups include phenyl, 1-naphthyl, 2-naphthyl, indanyl, indenyl, dihydronaphthyl, fluorenyl, tetralinyl, and 6,7,8,9-tetrahydro-5H-benzo[a]cycloheptenyl. In certain examples, aryl groups include those having a first carbocyclic, aromatic ring fused to an aromatic or aliphatic heterocycle, for example, 2,3-dihydrobenzofuranyl. The aryl groups herein are unsubstituted or, when specified as “optionally substituted”, can unless stated otherwise be substituted in one or more substitutable positions with various groups, as described below.

The term “heteroaryl” or “Het” refers to an aromatic ring system containing at least one heteroatom selected from nitrogen, oxygen and sulfur in an aromatic ring. Most commonly, the heteroaryl groups will have 1, 2, 3, or 4 heteroatoms. The heteroaryl may be fused to one or more non-aromatic ring, for example, cycloalkyl or heterocycloalkyl rings, wherein the cycloalkyl (Cak) and heterocycloalkyl (Hca) rings are described herein.

The compounds described herein can also be provided in prodrug form. “Prodrug” refers to a derivative of an active compound (drug) that undergoes a transformation under the conditions of use, such as within the body, to release the active drug. Prodrugs are frequently, but not necessarily, pharmacologically inactive until converted into the active drug. Prodrugs are typically obtained by masking a functional group in the drug believed to be in part required for activity with a progroup (defined below) to form a promoiety which undergoes a transformation, such as cleavage, under the specified conditions of use to release the functional group, and hence the active drug. The cleavage of the promoiety can proceed spontaneously, such as by way of a hydrolysis reaction, or it can be catalyzed or induced by another agent, such as by an enzyme, by light, by acid, or by a change of or exposure to a physical or environmental parameter, such as a change of temperature. The agent can be endogenous to the conditions of use, such as an enzyme present in the cells to which the prodrug is administered or the acidic conditions of the stomach, or it can be supplied exogenously. A wide variety of progroups, as well as the resultant promoieties, suitable for masking functional groups in the active drugs to yield prodrugs are well-known in the art. For example, a hydroxyl functional group can be masked as a sulfonate, ester or carbonate promoiety, which can be hydrolyzed in vivo to provide the hydroxyl group. An amino functional group can be masked as an amide, carbamate, imine, urea, phosphenyl, phosphoryl or sulfenyl promoiety, which can be hydrolyzed in vivo to provide the amino group. A carboxyl group can be masked as an ester (including silyl esters and thioesters), amide or hydrazide promoiety, which can be hydrolyzed in vivo to provide the carboxyl group. Specific examples of suitable progroups and their respective promoieties will be apparent to those of skill in the art

The compounds disclosed herein can also be provided as N-oxides.

The presently disclosed compounds, salts, prodrugs and N-oxides can be provided, for example, in solvate or hydrate form.

As will he apparent to those of skill in the art upon consideration of the present compounds, certain compounds can be enriched at a given position with a particular isotope of the atom at that position. For example, compounds having a fluorine atom, may be synthesized in a form enriched in the radioactive fluorine isotope ¹⁸F. Similarly, compounds may be enriched in the heavy isotopes of hydrogen: deuterium and tritium; and similarly can be enriched in a radioactive isotope of carbon, such as ¹³C. Such isotopic variant compounds undergo different metabolic pathways and can be useful, for example, in studying the ubiquitination pathway and its role in disease.

The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.

Oily suspensions can be formulated by suspending the active ingredients in a vegetable oil, for example araehis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents and flavoring agents may be added to provide palatable oral preparations. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents or suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, can also be present.

Pharmaceutical compositions can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil or a mineral oil or mixtures of these. Suitable emulsifying agents can be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions can also contain sweetening and flavoring agents.

In some embodiments, the pharmaceutically acceptable carrier, diluent, or excipient is not water. In other embodiments, the water comprises less than 50% of the composition. In some embodiments, compositions comprising less than 50% water have at least 1%, 2%, 3%, 4% or 5% water. In other embodiments, the water content is present in the composition in a trace amount.

In some embodiments, the pharmaceutically acceptable earlier, diluent, or excipient is not alcohol. In other embodiments, the alcohol comprises less than 50% of the composition. in some embodiments, compositions comprising less than 50% alcohol have at least 1%, 2%, 3%, 4% or 5% alcohol. In other embodiments, the alcohol content is present in the composition in a trace amount.

Syrups and elixirs can be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol, glucose or sucrose. Such formulations can also contain a demulcent, a preservative, flavoring, and coloring agents. The pharmaceutical compositions can be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension can be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parentally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils can be employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

Compounds of structural formulae (I)-(III) can also be administered in the form of suppositories, e.g., for rectal administration of the drug. These compositions can be prepared by mixing the compound with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.

Compounds of structural formula (I)-(III) can also be administered parenterally in a sterile medium. The drug, depending on the vehicle and concentration used, can either be suspended or dissolved in the vehicle. Advantageously, adjuvants such as local anesthetics, preservatives and buffering agents can be dissolved in the vehicle.

The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 100 mg, more usually about 10 to about 30 mg, of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.

The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound described herein. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, 0.1 to about 500 mg of the active ingredient of a compound described herein.

The tablets or pills can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like.

The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. it will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts.

The therapeutic dosage of the compounds can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound described herein in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds described herein can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

The compounds described herein can also be formulated in combination with one or more additional active ingredients which can include any pharmaceutical agent such as anti-viral agents, vaccines, antibodies, immune enhancers, immune suppressants, anti-inflammatory agents and the like.
